One Cool Guy, or OCG, was a third wave ska band from Union, New Jersey. OCG was founded in 1997 by a group of Union High School musicians. The group's members were Stuart Kamratz, Keith Eberle, Nick Afflitto, Peter Sibilia, Mark Fonseca Rendeiro, Dave Paiva, and Mike Struening. Later that same year, Chris Paszik joined the band along with technician Jeff "Johnny Benitez" Pereira. With the break up of New Jersey ska band the Royalties, Dan Ross was added to the line up.
